You can bind a static route with a detected group. The Auto Detect function will then detect the 

reachability of the static route through the path specified in the detected group. 

z 

The static route is valid if the detected group is reachable. 

z 

The static route is invalid if the detected group is unreachable. 

 

You need to create the detected group before performing the following operations. 

 

Follow these steps to configure the auto detect function for a static route: 

Enter system view

interface-number | next-hop } [ preference

Using Auto Detect can help realize VLAN interfaces backup. When data can be transmitted through two 

VLAN interfaces on the device to the same destination, configure one of the VLAN interface as the 

active interface and the other as the standby interface. The standby interface is enabled automatically 

when the active fails, so as to ensure the data transmission. In this case, the Auto Detect function is 

implemented as follows: 

z 

In normal situations (that is, when the detected group is reachable), the standby VLAN interface is 

down and packets are transmitted through the active VLAN interface. 

z 

When the link between the active VLAN interface and the destination faults (that is, the detected 

group is unreachable), the system enables the backup VLAN interface. 

z 

When the link between the active VLAN interface and the destination recovers (that is, the detected 

group becomes reachable again), the system shuts down the standby VLAN interface again. 

 

You need to create the detected group and perform configurations concerning VLAN interfaces before 

the following operations. 

 

Follow these steps to configure the auto detect function for VLAN interface backup:
